Copying buddy lists between 2 iMessages accounts
On each Mac that I have access to, I use a different AIM chat account. This way my correspondents can see where I am. It suffices for them to have the relevant mac-specific AIM screen names in the contacts entry they maintain of me.
Maybe this isn't intended usage (I could use just one AIM screen name and set a location specific "available" message on each of those macs).
Anyway, when first using a new AIM screen name on a new Mac, here is how you transfer your buddy names.
Make sure both AIM screen names are set up and enabled in the preferences.
Also UNCHECK de box General>Buddy List>Show all mij accounts in one list.
Then use Cmd-1 and Cmd-2 to show the two buddy lists pertaining to those two AIM accounts.
And start dragging buddy names that you want to keep to the new AIM account.
After that, you can disable the old AIM account in the preferences, and Messages will now allow you to assume the new identity when communicating with the newly defined buddies.
Done!
Hope this helps.
PS (somewhat unrelated axe I like to grind):
IMHO, Apple has made iChat/Messages/FaceTime sooo fragmented (between OS & app versions)(hence the anti-theme of an "ecosystem") that fewer people are using Apple's /texting/voice chat/video chat/ facilities.
Years ago, all my Mac friends were using iChat almost exclusively. These days, you hardly see any of them on line...
With iOS, Apple is about to miss a unique opportunity to pull Skype-users (and others) into Apple's chat ecosystem (provided it orchestrates Skype integration well). But I am afraid the opposite is happening.
